Change the setting index.highlight.max_analyzed_offset to your limit which is possible for you.

[aswinikumari]

the following curl command is used to set the offset, however it failed

curl -XPUT http://localhost:9200/_settings -H "Content-Type: application/json" -d '{ "index.highlight.max_analyzed_offset": 100000 }'

Please correct me if this curl command is correct

[aswinikumari]

This is the error message

Hey @aswinikumari,
your curl command want´s to override the global settings, but you must configure it on a specific index, which requires an higherindex.highlight.max_analyzed_offset

Here you find an example:

Curl-Command

curl -XPUT "localhost:9200/your_example_index/_settings" -H 'Content-Type: application/json' -d'
{
    "index" : {
        "index.highlight.max_analyzed_offset" : 100000
    }
}
'

At least that's how I would understand it.

You can read more about updating indice settings here

Best regards,
Robert

Hi Team,

I'm able to increase the index.highlight.max_analyzed_offset = 100000, however Elasticseach throws error again as below

Caused by: java.lang.IllegalArgumentException: The length of text to be analyzed for highlighting [1126818] exceeded the
_ allowed maximum of [100000]. This maximum can be set by changing the [index.highlight.max_analyzed_offset] index level_
setting. For large texts, indexing with offsets or term vectors is recommended!

So, is there a way to turn of the highlighter, or to change the default boundary character?

This is urgent
